Magic exists in a set of spectrums, these spectrums are defined in Magic Types below. These spectrums range from 0 - 10, in ether direction. A side from the affinity mechanics below, how or even if magic is used, or if it is even called magic is DBS
The only how that is not DBS is affinity. As magic is used (whatever the term "use" that might be DBS), a creature develops affinity for that type of magic by 1 point per use up to the cap of 10 (you move along the spectrum by 1 point, so if you were cold 4 and used heat, you would be cold 3). A creature is always weak to its opposing type affinity. I.E. A creature that has a high affinity for heat will be weak against cold, or vise versa.
